摘　　要：详细分析了在多假目标干扰存在情况下,雷达检测性能受影响程度,并分别从定性和定量2个方面进行仿真分析。分析结果表明,无论哪种CFAR检测器,在多假目标干扰存在的情况下,其检测性能都有不同程度下降,且其下降程度与假目标数目、假目标密集度和多假目标分布特性等密切相关。The radar detection performance is analyzed both from qualitative and quantitative aspects with the jamming of multi-false target existing. The results reveal that whatever type of CFAR detector is, all the detection performances will decline in different degrees, which is in relevant to the number, density and the distribution of targets.
